COCK.

Applicatidn filed December 30, 1916.

To all whom it may concern:

Be it known that l, Janus A. BUMr, a citizen of the United States, residing at Malta, in the county of Morgan and State of Ohio, have invented certain new and useful Improvements in (locks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in cocks and has relation more particularly to a device of this general character wherein a turning plug is employed; and it is an object of the invention to provide a novel and improved device of this general character whereby the cock may be automatically drained when the plug is in closed adjustment.

It is also an object of the invention to provide a cock having novel and improved means whereby the same may automatically drain, when closed, irrespective of its angle.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved cock whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use,

all will be hereinafter more fully set i forth.

The novel features of the invention will hereinafter be definitely claimed.

in order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is an elevational view with a portion broken away of a cock constructed in accordance with an embodiment of my invention;

Fig. 52 is a vertical sectional view taken through the device as herein embodied with the turning plug in open adjustment; and

Fig. 3 is a vertical sectional view taken through the device as herein embodied with the turning plug in closed adjustment.

As disclosed in the accompanying drawings, C denotes a casing of conventional type or design and which is provided with the passageway 1. The passageway 1 is intersected by the turning plug P disposed entirely through the casing C and preferably at right angles to the passageway 1 and said plug P has disposed therethrough the port 2 adapted to register with the passageway 1 to permit the flow of liquid Specification of Letters Eatcnt.

through the casing C. The port 2 is of such configuration and dimensions as to permit the plug 1 to close the passageway 1 upon giving the plug P substantially a onequarter turn in either direction.

The plug P circular in cross section and tapered longitudinally and fits snugly within the casing C. I have found itof particular advantage to provide a construction whereby the plug may be turned in either direction in order to control the flow through the passageway l as by this arrangement the plug P is caused to snugly engage within its seat.

The side walls of the passageway 1 at substantially the longitudinal center thereof have produced therein the grooves or channels 3 preferably arranged at right angles to the passageway 1 and which communicate with the radially disposed grooves or channels 4 produced in an outer face of the casing G. The channels 3 are preferably disposed in a direction toward the smaller end of the plug P and are gradually enlarged from their inner ends. lhe grooves 3 are of such a length as to have their inner ends terminate at substantially the axial center of the port 2, whereby communication is afforded with such port when the plug P has been adjusted or given a quarter turn to close the passageway 1.

It has becn found in practice that it is essential. to employ two opposed grooves or channels i so that one of said grooves or channels can serve as an air vent to assure the proper chaining of the fluid through the second groove or channel 3. By this particular arrangement it will be at once selfevident that an automatic draining is assured irrespective of the angle in which the cock may be arranged.

The smaller end of the plug P, as herein embodied, is provided with the threaded extension 5 upon which is mounted the binding washer 6. he inner face of this washer 6 is provided with the radial grooves or channels 7 adapted to register with the grooves or channels 4 hereinbefore referred to in order to afford enlarged ports in communication with the grooves or channels 3 to facilitate the entrance of air or the discharge of the liquid.

Also engaged with the threaded extension 5 is the holding nut 8 serving in a manner and for a purpose which is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

From the foregoing description, it is thought to be obvious that a cock constructed in accordance with my invention is of an extremely simple and comparatively in expensive nature and isparticularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. A cock consisting of a casing provided with a passageway, a turn plug rotatably supported by said casing and intersecting said passageway, said plug being provided with a port adapted to register with the passageway of the casing when the plug is in one position, said plug serving to close the passageway when adjusted in a second position, the opposed faces of the passageway of the casing being provided with groovesleading to the atmosphere, said grooves being of such a length as to afford communication with the port of the turning plug when said plug is in closed adjustment.

2. A cock consisting of a casing provided with a passageway, a turn plug rotatably supported by said casing and intersecting said passageway, said plug being provided with a port adapted to register with the passageway of the casing when the plug is in one position, said plug serving to close the passageway when adjusted in a second Copies of this patent may be obtained for position, the opposed faces of the passageway of the casing being provided with grooves leading to the atmosphere, said grooves being of such a length as to afford communication with the port of the turning plug when said plug is in closed adjustment, a washer mounted upon an end portion of the plug and provided in its inner face with grooves adapted to communicate with the grooves of the casing, and means for holding said washer in applied position upon the plug.

3. A cock consisting of a casing provided with a passageway, a turn plug rotatably supported by said casing and intersecting said passageway, said plug being provided with a port adapted to register with the passageway of the casing when the plug is in one position, said plug serving to close the passageway when adjusted in a second position, the opposed faces of the passageway of the casing being provided with grooves leading to the atmosphere, said grooves being of such a length as to afford communication with the port of the turning plug when said plug is in closed adjustment, a washer mounted upon an end portion of the plug and provided in its inner face with grooves adapted to communicate with the grooves of the casing, and means for holding said washer in applied position upon the plug, the face of the casing opposed to the washer being provided with grooves in register with the grooves of the washer.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
